It is a very good hair serum that works wonderfully for my thick frizzy hair. I like using serum instead of cream or lotion because it feels more moisturizing to the hair. I've used it on wet hair, damp hair, dry hair, second day hair, after flat iron hair, and it always gets the job done. It smooths out my hair without weighing it down, adds a little bit of shine, and keeps my hair smooth and soft after styling. I think the key is to only apply the necessary amount for your hair type and length, over using it might have the opposite effect.

This was a great find for fine hair, as were all of the Youth Boost products. Shame the line's been discontinued. Sprayed directly onto your roots, it added nice volume and lift--no gunk. Smelled great and was very affordable, too. If Tresemme brought it back, I'd definitely repurchase.

Not my favorite product, but a great value. I typically get the strongest hold (5) b/c I have ringlets underneath and wavy on top - Crunchy hair- Leaves white flakes in hair- Feels very watered down - I wouldn’t buy this product again and wouldn’t recommend it.
